The pneumatic installation of the LOGO!MAT Diverter has to be done according to the pneumatic schematics to guarantee proper function of the unit. The connections for the pneumatic tubes are designed for a tube diameter of 6 mm. Please ensure that pressurized air is dried and filtered and the pressure is in the stated range. LOGOMAT automation systems, Inc. recommends two 3/2- or one 5/2- or one 5/3-way valve for the control of the cylinder.
 
Exhaust flow controls have to be used for both air lines in any case! The air flow should be set so that the diverter arm needs at least two seconds from one end position to the other.

The control of the Junction / Diverter has to be done automatically!
 
To control the LOGO!MAT Junction please use the following recommendations:
  1. The arriving pallet must be stopped in front of the Junction area by a LOGO!MAT Stop Unit. The presence of the pallet must be detected by the pallet present sensor.
  2. To release the pallet, the Junction area has to be confirmed to be free of pallets.
  3. No controls of the Junction arm is required, because it gets moved [opened or closed] by the pallet itself.
  4. The entire process is deemed complete if the pallet has overrun the Hi level sensor behind the Junction area.

To control the LOGO!MAT Diverter please use the following recommendations:
  1. The arriving pallet must be stopped in front of the Diverter area by a LOGO!MAT Stop Unit. The presence of the pallet must be detected by the pallet present sensor.
  2. Depending on the desired conveyor flow direction, the Diverter must be opened or closed.
  3. If the required position of the Diverter is displayed permanently and the required area to the conveying direction is confirmed to be free, the stop unit can release the pallet.
  4. The entire process is deemed complete if the pallet has overrun the Hi level sensor behind the diverter area.
  5. The Diverter arm can stay in the position and does not necessarily proceed to a defined home position.

For the electrical installation, sensors have to be installed in the provided brackets. The wires have to be protected against chafing and secured against unintentional removal. Please pay attention to the correct switching distance and the right sensor size. The controls of the sensors and the used logic can influence the function and the entire performance of the Diverter / Junction Unit dramatically. This is the responsibility of the operating company.
 
The drive motor of the electrical LOGO!MAT Diverter Unit has to be connected electrically via a frequency converter according to the documentation of the motor manufacturer. The frequency converter must be adjusted so that the movement of the diverter arm (opening and closing) takes more than two seconds.

The friction clutch is a safety element and has to be adjusted properly for the operator safety. It gets preconfigured by LOGOMAT automation systems, Inc. before delivery. If further adjustments are necessary, please check the operating requirements first. A clutch that has been set too strong may lead to a mechanical overloading of the diverter drive which has to be avoided in any case.
 
You can find more information in the documentation of the friction clutch.
 
To adjust the friction clutch, please proceed as follows:
  1. Disconnect the electrical and pneumatic supply of the entire conveyor system and secure against reconnection.
  2. Remove the outer safety covers to get free access to the friction clutch.
  3. Remove the locking bolt of the friction clutch so that the adjusting nut can be turned.
  4. Pre-level the two adjoining conveyor tracks. Release the locking nuts on the leveling feet and adjust the height of the conveyor segment by turning the threaded spindle.
  5. Tighten the adjusting nut by one increment.
    The friction clutch is not infinitely variable. However, it should be adjusted so that the diverter arm can be stopped easily by hand (manual) during operation and movement.
  6. Tighten the locking bolt and make sure that the mark ups match and the holes align.

All described installation steps and adjustments are shown with the LOGO!MAT Diverter. However, everything specific in regards to the LOGO!MAT Junction is mentioned.
 
The installation must be performed by trained and authorized personnel only.
A proper installation and alignment is one of the major factors for a proper and reliable operation.
 
To install the LOGO!MAT Diverter / Junction Unit, please proceed as follows:
  1. Remove the tape from the conveyor sections and diverter / junction arm which is used to secure all items during transportation.
  2. Loosen both cross connectors, that are pre-mounted under the main conveyor track and move them to the middle of the diverter / junction area.
  3. Take the entire rotation unit off, including the diverter / junction arm and the inner corner of the diverter / junction with the upper gusset plate by removing the upper mounting bolts
  4. Pre-level the two adjoining conveyor tracks. Release the locking nuts on the leveling feet and adjust the height of the conveyor segment by turning the threaded spindle.
  5. Set up the two conveyor segments, to be connected at the diverter or junction unit at an exact 90 degree angle.
  6. The inner corner assembly and the rotation unit can be used as an alignment tool. The notches of the top rail connectors have to fit into the cutouts in the upper gusset plates. That ensures an installation in a 90 deg. arrangement.
  7. Slide the cross connecters so that they line up with the adjoining conveyor extrusions as they will be bolted to these extrusions (as shown in the figure below). These connectors align the accurate height level of both conveyor tracks to each other, but the correct height has to be adjusted to ensure a safe and proper function.
  8. Level the diverter / junction area in all directions to the entire conveyor height, by adjusting the leveling feet. Tighten all connecting bolts and anchor the leg sets to the floor.
  9. Move the diverter arm manually and check the unit for possible mechanical blockages.
  10. Connect the pneumatic and electrical connections and check the function of the entire unit. Make sure that the opening and closing speed of the arm is adjusted so that it takes at least 2 sec.
Make sure that all chain covers are snug in the slot of the plastic corner, otherwise the covers will lift the plastic corner and block the diverter arm mechanically!

  9. Reconnect the Stop Unit pneumatically.
  10. Check the function of the Stop Unit and adjust according to the documentation and setting instructions if necessary.
 

Only authorized personnel are permitted to install a Stop Unit. Before the Stop Unit can be fitted, you should unpack, clean and look for any damage. If there is damage, document and repair before starting the installation.
 
Attention must be paid to the positioning of the Stop Unit. There must be at least a distance of 20 mm between the adjoining roller (outer diameter) and the Stop Unit body in the end and home position to avoid possible pinch points.
 
A displacement of a Stop Unit can also be done according to the following installation instructions:
  1. Disconnect the Stop Unit from the compressed air supply to avoid injuries.
  2. Remove the mounting clamps from one side of the base plate and loosen the other side slightly.
  3. Place the Stop Unit into the lower slot of the extrusion with the remaining two clamps. Lightly tighten the clamps and install the remaining mounting clamps on the other side. Adjust the unit and partially tighten the clamping bolts. Please pay attention to the direction of the conveyor flow (note at the drive station) and the arrow at the Stop Unit housing that the operation direction will fit to the flow direction.
  4. Check the position of the Stop Unit by pushing a pallet against the Stop Unit until the stop pin locks the pallet into position and the stop is at its cushioned end position of the horizontal movement.
  5. Remove pallet and adjust the Stop Unit to achieve the required pallet stop location, if necessary.
  6. Once the position is correct, completely tighten all four clamping bolts and connect the pneumatic air supply tubes. (Attention must be paid to the correct locking of the clamping bolts to the conveyor profile.)

LOGO!MAT Walk-On - Series: Manual Docking Cart


Manual Docking Cart 1
Manual Docking Cart 2

The LOGO!MAT Walk-On Manual Docking Cart is our design for manual pull off and re-entries of pallets within a conveyor system. Especially in large and complex layouts and processes there are needs to take parts to different areas for repair after a failed testing. Those parts have to be re-introduced into the line to be tested again.

The Walk-On Manual Cart is based on a piece of low profile gravity conveyor track that can be moved around on lockable caster wheels. The height of the Manual Cart is set to the conveyor height where the Cart will dock to and the handle has adjustable grips for the operator. 

An integrated docking mechanism interfaces with a counterpart on the conveyor line and locks the Cart in position. It also automatically releases mechanical stops on the Cart to allow the pallet flow. By releasing a mechanical indexing plunger the Cart can be taken off the track and the mechanical locks directly block the lines. The presence of a Manual Docking Cart can be sensed by an inductive sensor mounted to the stationary conveyor track.

A bi-directional Docking Cart with two docking devices is also available to allow the reintroduction of a pallet in the same orientation as it was removed wiithout rotating it.
